CHAPTER IV RESEARCH FINDING
A. Data Description
After the research is held in MTs Pembangunan UIN Jakarta, the score of test-both pre-test and post-test- is ready to analyze. The pre-test is given to the
student before the treatment in experiment class is held. Then, the post-test is given after three times treatment in the same class. Moreover, the writer also
takes pre-test and post-test score from control class without any treatment. The result of pre-test and post-test both experiment and control class are
shown in the table below:
